ertussen-STEEL sinn FRAME.

Application filed April 5,

This invention relates to a new and improved pressed steel side frameand more particularly to a side frame having journal boxes securedthereto yby welding, in such manner as to become an integral part there-Pressed steel side frames have heretofore been made and have beensecured to journal boxes in various manners, as, for example, by beingbolted to a horizontal face of the frame. According to the presentinvention the journal box is fitted into an ope-ning in the side frameand is thus secured against movement by the surrounding portion of theside frame. It is welded to the side frame to secure it lixedly to theframe as an integral part thereof.

It is an object of the present invention to provide a side framestructure having journal boxes integrally secured thereto and enclosedby a portion of the side frame.

It is a further objectto provide a construction of this character inwhich the side frame is formed of a pair of members welded together andin which they journal box extends through registering openings in thetwo side frame members and is welded to both said members.

' @ther and further objects will appear as the description proceeds.

I have illustrated a preferred embodiment of my invention in theaccompanying drawing, in which- Figure 1 is a view of one-half of a sideframe constructed according to the present invention;

Figure 2 is a front view of Figure 1;

Figure 3 is a view of Figure 2 as seen from the left;

Figure 4 is a section taken on line 4-4 of Figure 2; and l I" Figure 5is a Section taken on line 5 5 of Figure 2.

The side frame as shown comprises two pressed steel members 11 and 12,the inwardly extending flanges of which are welded together along theline 13. As shown in Figure 4, the side frame members are U-shaped incro-ss section through some portions of their area, these U-shapedmembers being welded together. In such p0rtions of the side frame asshown in detail in Figure 5, which is a section of the lower tensionmember, the side frame members 1924. Serial No. 704,314.

are L-shaped and are only'secured together by welding on a single line.

Each side frame member 11 and 12 has at each end an opening formedtherein, the opening being surrounded by an inturned flange 14. As shownin Figure 3 these flanges 14 and 15 abut on the line 13 and are weldedtogether. These flanges are formed by drawing down the metal from theinterior of the opening surrounded by the flange. Y

The lower flanges 11 and 12 shown welded together in Figure 5, arewelded to the flanges 14 and 15 at 16 as indicated in Figure 2, tostiften the construction. The

journal boxes 17 which are preferably formed of pressed steel arefitte'd into the opening encircled by the flanges 14 and 15. Thesejournal boxes extend through upon both sides of the side frame and arewelded to both of the members 11 and 12. They thus aid in strengtheningthe connection between the two members and adding to the rigidity of theconstruction.

These journal boxes, as shown in Figure 3, have the hinge member 18welded thereto and also the member 19 welded inside the box, this memberserving to maintain the usual dust guard in position.

I have shown one preferred form of my invention by way of illustrationbut it is to be understood that I contemplate such changes andmodifications to meet varying conditions as are within the spirit andscope of the Vappended claims.

I claim:

1. Side frame construction comprising a side frame formed of pressedsteel, an opening formed in the frame surrounded by a transverselyextending flange, and a journal box fitted into the opening.

` 2. Side frame construction comprising a pair of pressed steel sideframe members having inwardly extending flanges welded together,registering openings formed in the members, and a journal box extendingthrough said openings and welded to the members.

3. Side frame construction comprising a pair of pressedfsteel side framemembers having inwardly extending flanges welded togetherI registeringopenings formed in the members surrounded by inwardly extending flanges,and a pressed steel journal box fitted in said reistering openings andbearing against the anges.

el. Side frame construction comprising u pair of pressed steel sideframe members having inwardly extending anges Welded together,registering openings formed in the members surrounded by inwardlyextending anges, and a pressed steel journal bof; Fitted in saidregistering openings and bearing against the lizinges, said journal bonYbeing Welded to both suid frame members.
